... of horizontal fixed fins are attached between two hulls for the reduction of pitch motions, the fin effects were confirmed by the model tests. Running trims of the vessel are changed depending on the fins, so the seakeeping behaviors are analyzed with consideration of ship attitude. RMS values of pitch, roll...

...) was numerically solved and the volume of fluid (VOF) approach was used to simulate the flows. The wavelengths varied from half the ship length to twice the ship length and the design speed was selected for the velocity. The heave and pitch motions were calculated along with the added resistance and the wave...

... programs didn t consider the motions of foundation. Therefore, deviation is present inevitably. This paper is mainly focused on the effect of pitch motion on the aerodynamic loads and output power performance of the floating wind turbine. Pitching response of the floating foundation was figured out...
